So, your question is, how to write a rule to detect someone going to eBay?

we are trying to write simple rules, we have had some success so far,
a little at a time, we are now trying to write a small rule to alert if someone
is visiting a specific site, say www.ebay.com <http://www.ebay.com/>

so far we have this in a file called testing.rules.

# testing.rules
alert icmp any any -> any any (msg:"$$$$$TESTING rule$$$$$"; sid:1000001;)


its rudimentary, we know, but its working ok. before we uncomment the config and include
a bigger set of rules, we want to regresstion test them in their simplest form.

if someone replies, and since I am not 100% sure how this list works yet,
could you please copy me here? maryandrews22 () gmail com <javascript:_e({}, 'cvml', 'maryandrews22 () gmail com');>

many thanks,
